SOAlE-BUBBLE-BLOWING DEVICE.

To all whom it may concern Be it known that I, GEORGE M. LrrTLn, acitizen of the United States, residing at Pittsburgh, Allegheny county,State of Pennsylvania, have invented a new and useful Improvement inSoap-Bubble-Blowing Devices, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,forming part of this specification, in wh1ch- Figure 1 is a perspectiveView partially 1n sectien of one form of my soap-bubbleblowing device;Fig. 2 is a longitudinal section of Fig. 1; Fig. 3 is a sectional viewon the line III-111 of Fig. 2; and Fig. 4 is a sectional view similar toFig. 2 of another form of soap-bubble-blowing device. This inventionrelates to an improvement in soapbubble-blowing devices which can becheaply and readily constructed and with which bubbles of large diameterand of beautiful'colors can be quickly blown.

One of the objects of my invention is to i provide a device having abubbleblowing opening of large diameter, together With means for quicklyintroducing a large amount of air into the bubble being blown, so as toblow the bubble before much evaporation takes place.

Another object is to provide a device with a damper or check which willmaterially retard the exhaustion of the bubble when the blower takesanother breath to increase the size of the bubble, and which checkdevice will also act as a diffuser to break up the direct blast of air,so that the air will be distributed equally throughout all portions ofthe blowing opening.

A further object is to surround the blowing opening with a liquidcontainer for feeding liquid to the bubble during the blowing operation,and thereby avoid the thinning of the film to the breaking point beforea bubble of large size has been blown.

, The precise nature of my invention will be best understood byreference to the accompanying drawings, which will now be described, itbeing premised, however, that various changes may be made in the detailsof construction of the several parts, without departing from the spiritand scope of my invention as defined in the appended claims.

Referring to Figs. 1 to 3, the numeral 2- designates the body of theblower, which is Specification of Letters Patent.

of a conical form. lhe smaller end is provided with a mouth piece 3,having an openmg therethrough which is arranged to be Patented Nov. 3,1914. Application filed August 6, 1913; Serial No. 783,364. i

inserted'through the larger end, so thatit can readily be changed whenthe blower is to be used by different persons. The larger or bubbleblowin'g end of the device is provided with an absorbent rim 4, whichmay be formed of any material capable of absorbing and holding soapywater, and which may be attached to the end in any desired manner, suchas by a waterproofcement.

The numeral 5 designates a damper which I have shown in the form of ascreen and which is inserted in the blower between its ends, and isdesigned to break upjthe, currents of air from which the bubble isblown,

and also to form a damper or checking device to prevent the bubble fromexhausting rapidly when the blower takes another breath. Extendingthrough the wall of the blowing device between the end containing themouth piece and the damper 5 isan opening 6, which is of verylargediameter ,and' may be approximately the size. ofthe bubble-blowingopening. i

The damper o and the mouth piece 3 are made removable so. that both the.body portions and the dampers can be stacked to occupy a minimum amountof space during shipment and. storing. The damper 5 may be formed fromwire screening whichpis pressed into suitable shape, or may be formed oftextile material of very coarse open mesh which will be provided with areinforcing ring of the proper shape. This damper also acts as areinforce to retain the body in proper shape when in use. If desired,the entire body may be formed of an absorbent material such as felt orfabric of any kind, but for economy, I prefer to form the body of tin orwaterproofed paper and attach tot-he bubble-blowing end a tape ofabsorbent material. I i

In Fig. 4, I have shown a one-piece construction similar to that shownin Figs. 1, 2 and 3, which is formed of suitable material and isprovided with an integral mouth piece having an opening therethrough. In

this form, 2 designates the body, 3 the mouth piece, and 3 a tubeextending inwardly from the end of-the mouth piece.

The operation of the device is as follows: a solution of soap in wateris first made up in any suitable receptacle and the tape 4: is dippedinto the solution. It is then re moved from the solution, a film ofsolution closing the opening. The operator then blows through the mouthpiece, and during the blowing, air will be sucked in through the opening6 by means of the injector action, which air, together with the airblown through the mouth piece, will pass through the damper 5 and willbe broken up, so that the pressure of air will be approximately equal atall points on the bubble-blowing end as it passes to the bubble beingblown. As the operator takes another breath, the damper 5 will prevent,in great measure, the escape of air from the bubble, so that it will notbe materially reduced in size during the several intervals of time thatthe operator is not blowing. During the blowing operation, the bubblewill draw water from the tape 4, and thereby prevent the film fromthinning out to the bursting point before a large bubble has been blown.

I prefer to make the blower of general conical form, although goodresults may be obtained from blowing devices made of different forms.

The advantages of my invention result from the provision of a blowerhaving a large bubble-blowing opening, together with an air inletopening of large area between the bubble-blowing end and the mouthpiece. Further, from the provision of a damper for breaking up theblasts of air and also for minimizing the escape of air from the bubblebetween breaths of the blower. Further, from the provision of means forsupplying liquid to the bubble during the blowing operation.

I claim:

1. A bubble-blowing device of taper form, having a large bubble-blowingopening at one end, there being a small opening through the other end,and also an auxiliary air-supplying opening of large diameter throughthe wall of the device between the ends thereof, substantially asdescribed.

2. A bubble-blowing device having a large bubble-blowing opening at oneend, there being a small opening through the other end, there also beingan air-suppplying opening of large diameter through the wall of thedevice and between the ends thereof, and a damper between thebubble-blowing end-and the last named opening, substantially asdescribed.

3. A bubble-blowing device having a bubble-blowing opening at one end, amouth piece having an opening through the other end, an air-supplyopening of large area between the ends, and a screen between theairsupply opening and the bubble-blowing end, substantially asdescribed.

l. A bubble-blowing device having a bubble-blowingopening at one end, amouth piece having an opening through the other end, an air-supplyopening of large area between the ends, and a removable screen betweenthe air-supply opening and the bubble-blowing end, substantially asdescribed.

5. A bubble-blowing device having a bubble-blowing opening at one end, aremovable mouth piece having an opening through the other end, anair-supply opening of large area between the ends, and a removablescreen between the air-supply opening and the bubble-blowing end,substantially as described.

6. A bubble-blowing device having a bubble-blowing opening at one end, aprimary air inlet, a secondary air inlet of larger area, and animpedance between the secondary air inlet and the bubble-blowingopening; substantially as described.

In testimony whereof, I have hereunto set my hand.
